Application filed May 2S,

To all whom, t may concern Be it known that l lil/licitar, PIsUn-x acitizen of Poland, residing at Chicago, in the Y tachably retainingwindowA panes in Vsash Y frames. i

The primary object of the invention is to provide a simplifiedconstruction of window sash frames with readily operable means forexpeditiously securing .a Vpane of glass therein, and wherein thesecuring means is readily removable from the interior 0f the dwellingfor inserting a new pane of glass when found necessary or desirable.

Another object is to generally simplify and improve sash frameconstruction whereby a pane of glass may be readily secured in placethrough the medium of a simple means and the expenditure of a minimumamount of time and labor.

@ther objects will become apparent as the nature. of the-invention is.better understood,

and the invention consists in the novel form, combination andarrangement of parts hereinafter more fully described and shown in the,accompanying drawings, in which like reference characters indicatecorresponding parts throughout the several views.

seein-mg strip removed to reveal the keeper, and

.Figure 7 is a fragmentary perspective view of one of the sliding boltcarrying members or strips. Referring more in detail to the severalviews, the invention contemplates the construction of a rectangularframe composed of rigidly and permanently connected side members 5, atop member 6 and bottom member 7, these members being tongue and groovejointed or the like in the usual way, and the top member 6 beingprovided with a .longitudinal groove as at 7 for snug reception of theupper' edge portion of the window pane 8 whereby the `latter is engagedupon opposite sides in said top member of the frame. rihe inner faces ofthe side meinbers 5 and bottom member T ,are substantially flat, andthese members are provided with longitudinal inwardly` projecting ribs 9along their outer edges against which the remaining edge portions of thepane of glass are adapted to seat when contacting with the inner flatfaces of said frame members. The ribs 9 preferably have beveled surfacesso as to readily` shed rain or the like and a suitable packing materialmay be placed between the ribs and the glass as at 10 to maire the samewatertight and airtight.

The means for detachably fastening the pane of glass S against the ribs9 embodies three strips arranged to latly engage the inner faces of theside frame members 5 and the bottom frame members 7, the side securingor fasteningstrips 4being denoted by the numeral 1l, land thebottomsecuring strip being denoted bythe numeral 12.` Both oi the sidesecuring strips 11 are ofidentical construction and each includes a bodyportion of wocdhaving a flat end as at 13 abutting the inner surface ofthe upper frame member @and having `the other end of the same beveled.as at 14 to engage the adjacent beveled end of the lower securing strip12. The securing strips 11 and 12 are provided with longitudinal.elongated Vrecesses as at 15 in their outer faces, which recesses areeach covered by a strip of metal 16 for forming a chamber betweensaidmetal strip and the securing strip in which a sliding elongated bcltcarrying member 17 is movably retained. The member 17 Vis slightlyshorter than the securing strip which carries the same and the coverVstrip or plate 16 is fastened to the securing strip by means of screws18 or the like. Projecting outwardly from the opposite ends of eachsliding member 17 and rigid with the latter are angular bolts 19 whichslidably extend through longitudinally elongated slots 20 provided inthe strip or cover plate 16, and the end portions of the bolts 19 arearranged to ride into grooves 21 provided in the inner faces of theframe members 5 and 7 and beneath suitable keeper plates 22 fastened tosaid frame members across the recesses 21. rlhus by sliding the endsofthe bolts 19 beneath the keeper plates 22, the securing strips 11 and12 are efliectively held in place so as to secure the edges of the pane8 against the ribs 9, while when the sliding strip 17 is slid in theopposite direction, the ends of the bolts .are disengaged from saidkeeprplates so that the securing strip may be readily removed. Each ofthe securing strips is provided with a longitudinal elongated, andApreferably centrallv located slot 23 through which a stem 241 looselyprojects,

' said stem being rigid with and projecting` laterally from the slidingbolt carrying member of the securing' strip and having a threaded outerend with a nut 25 threaded thereon so that said nut may be grasped forsliding the strip 17 and its bolts into or out of engagement with thekeeper plates 22. Also, a suitable apertured bearing plate 26 isfastened to the securing strip about its slot v23 and a plate 27 restsupon the bearing plate 26 and upon a shoulder of the stem 24 so thatwhen the nut 25 is threaded onto said stem, the bolt carrying strip willbe releasably retained against sliding movement, the cover plate 27being provided with a small single aperture through which the pearance,and as the securing strips are located at the inside of the glass pane,the latter may not be removed from the exterior of the dwelling equippedwith a sash con structed in accordance with the present invention.

In the use of the present invention, the nuts 25 are loosened and thenthe same are actuated to slide the members 17 so as to disengage thebolts 19 from the keeper plates 22, whereupon the securing strips 11 and12 may be readily removed. The pane of glass is then inserted in theopen lframe so as to first direct its upper edge portion into the groove7', and then the same is swung inwardly at its lower portion so that theremaining edge portions of the glass engage the ribs 9. The securingstrips 11 and 12 are then placed into position as shown in Figure 1, andthe members 17 are slid longitudinally so as to engage the ends of thebolts 19 under the keeper plates 22. The

nuts 25 are then tightened and thesecuring strips then effectivelyretain the pane of glass in place, it being understood that a suitablerubber packing strip or the like as at 10 can be inserted between theglass and the ribs 9 if desired.

It is believed that the construction and operation as well as theadvantages of the present invention will be readily understood andappreciated by those skilled in the art from the foregoing description.

Minor changes may be made without departing from the spirit and scope ofthe invention as claimed.
